The difference between human body thermometers and industrial thermometers
The human body infrared thermometer is mainly used to measure the temperature of the human body, while the industrial infrared thermometer, as the name suggests, is mainly used in the industrial field. However, it must be clarified that there is no specialized medical or industrial infrared thermometer, as the manufacturing principles of infrared thermometers are consistent. There is only a distinction between high-precision, high distance coefficient ratio, high-performance infrared thermometers, and high-precision, low distance coefficient ratio, and low-performance infrared thermometers. As long as the emissivity of the infrared thermometer is set to 0.95 (the emissivity of human skin is generally this value, and even if there is a difference, the impact is only within 0.2 degrees), it meets the requirements of human temperature measurement.
One is that the human infrared thermometer has a small temperature range of 30-42.5 degrees, but the display accuracy is high. The industrial infrared thermometer has a large range, such as being able to measure -50 to 2200 degrees.
The second is that the human infrared thermometer needs to be close to the human body, within 1-15cm, and the industrial infrared thermometer needs to be greater than 1M. If measuring the temperature of molten steel, people cannot be too close, and some require around 10M. Measuring near and far mainly refers to the intensity of the infrared waves emitted by the thermometer. The infrared wave of the human body infrared thermometer is too strong and harmful to the human body, and it is not necessary.
Therefore, we can choose a suitable thermometer according to needs, which can be divided into three aspects: performance indicators, such as temperature range, spot size, working wavelength, measurement accuracy, response time, etc; In terms of environment and working conditions, such as environmental temperature, window, display and output, protective accessories, etc; Other options, such as ease of use, maintenance and calibration performance, and price, also have a certain impact on the selection of infrared thermometers.
